Disclosed are a group of surfactant-free methods for the manufacturing of polymer microspheres and microcapsules. The manufacturing processes involve droplet generation in the absence of surface-active substances and de-solvation of the droplets through solvent diffusion into a continuous phase composed of a mixture of amphiphilic solvent and water. The methods involve approaches for the manufacturing of isotropic polymer microspheres, core shell polymer microspheres, Janus microspheres, and microcapsules. In the manufacturing of isotropic polymer microspheres, polymer or polymer plus additive components are dissolved in water-immiscible organic solvent to obtain a dispersed phase. Mix of amphiphilic solvent and water is used as the continuous phase. The dispersed phase is dropletized in the continuous phase and therein de-solvated via solvent diffusion in the absence of surfactant to form solid isotropic microspheres. In the manufacturing of Janus microspheres, two polymer solutions each dissolved in water-immiscible organic solvent form a dispersed phase. Mix of amphiphilic solvent and water is used as the continuous phase. The dispersed phase is dropletized in the continuous phase and therein de-solvated via solvent diffusion in the absence of surfactant to form solid Janus microspheres. In the manufacturing of core shell polymer microspheres, a core solution in a solvent and a shell polymer solution dissolved in water-immiscible organic solvent form a dispersed phase. Mix of amphiphilic solvent and water is used as the continuous phase. The dispersed phase is dropletized in the continuous phase and therein de-solvated via solvent diffusion in the absence of surfactant to form solid core shell microspheres. In the manufacturing of microcapsules with polymer shell, a core solution in a solvent and a shell polymer solution dissolved in water-immiscible organic solvent form the dispersed phase. Mix of amphiphilic solvent and water is used as the continuous phase. The dispersed phase is dropletized in the continuous phase and therein de-solvated via solvent diffusion in the absence of surfactant to form microcapsules. By using these methods, the problems caused by the use of surfactants are eliminated, the use of toxic solvents is minimized, the throughput of the manufacturing processes is maximized, and the release of toxic solvents into the atmosphere and their resulting pollution are minimized while the solvents can be recycled.

Disclosed are an apparatus and a method for increasing a solid content in a reaction crystallizer. The apparatus comprises a discharging tube, a supernatant tube, a supernatant barrel and a gas collecting tube. The upper end of the discharging tube, the upper end of the supernatant tube and the lower end of the gas collecting tube are respectively connected to each other. The lower end of the discharging tube is submerged below the liquid surface in the crystallizer, the lower end of the supernatant tube is submerged below the liquid surface in the supernatant barrel, and the gas collecting tube collects gas that enters the discharging tube and the supernatant tube. A liquid level must be maintained above the junction of the discharging tube and the supernatant tube to ensure that the crystallizer and the supernatant barrel are always in liquid communication with each other, the liquid in the cyrstallizer being level with liquid in the supernatant barrel, and the supernatant barrel maintaining the liquid level therein by overflowing. When the crystallizer is added to, the liquid-solid mixture in the crystallizer automatically enters the discharging tube and slowly flows upward therein, during which the solid particles gradually sink and settle back into the crystallizer, while the supernatant continues to flow upward before entering the supernatant tube, and flows into the supernatant barrel, where it is discharged by overflowing. The method has the advantages of requiring a low investment and being easy to operate, and can effectively increase a solid content in the reaction crystallizer and control crystal morphology and particle size distribution.
